It is the foundation of the track and an important building to ensure the operation of the train. The railway subgrade is a geotechnical structure built to meet the conditions for track laying and operation. The existing technology uses bulldozer-rammed concrete piles for the construction of railway subgrades. Affected by geological factors, it is inevitable that there will be ups and downs during long-term use. The railway route is long, and the cost of transporting raw materials during maintenance is high and cumbersome and inconvenient.
